## Benefits of Secure Boot Feature
- **Protection from unauthorized bootloader images** - Secure Boot prevents booting unauthorized bootloader (GRUB) images via signature verification of the bootloader (GRUB) from UEFI.
- **Protection from unauthorized kernel images** - Secure Boot prevents booting unauthorized kernel images via signature verification of the kernel from GRUB bootloader.
- **Protection against malware and rootkits** - Secure Boot prevents loading malware/rootkits via chain of trust from UEFI to GRUB to Kernel using signatures verification.
- Compliance with Security By Design principle for boot protection.

## Abbreviations Used in This Guide
| Term | Description |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| BIOS and UEFI | Basic input / output system (BIOS) is a program fixed and embedded on a device's microprocessor that helps to initialize hardware operations.
Unified Extensible Firmware Interface (UEFI) offers users a faster and sleeker experience. It supports secure booting of the bootloader.
BIOS uses 16-bit mode and has a limited user interface, UEFI uses 32-bit or 64-bit mode and offers a more advanced graphical user interface. |
| MBR and GPT | Master Boot Record (MBR) is the information in the first sector of a hard disk or a removable drive.
GUID Partition Table (GPT) is introduced as part of the Unified Extensible Firmware Interface (UEFI) initiative.
GPT provides a more flexible mechanism for partitioning disks than the older Master Boot Record (MBR) partitioning scheme. |
| GRUB and GRUB2 | GRand Unified Bootloader (GRUB or GNU GRUB) is a Multiboot boot loader for Linux and other Unix-based OSes.
GRUB2 bootloader is the bootloader on x86 systems that is used to load the linux kernel or any other OS. GRUB2 is allowed to load by UEFI if its signature matches the signature in the UEFI’s whitelist DB. |
| ICS | Ivanti Connect Secure (ICS) provides a seamless, cost-effective SSL VPN solution for remote and mobile users from any web-enabled device to corporate resources. |
| ISA | Ivanti Secure Access hardware appliance. |
